Abstract

Of the various endocrine tumors affecting the pancreas, insulinomas and gastrinomas are the most common. In order to facilitate surgery, the localization of tumor is important. However, at the first time of presentation, the localization of tumor was often difficult by CT or ultrasonography because the tumor was relatively too small. The introduction of endoscopic ultrasonography has allowed high-resolution imaging of the pancreas that distinguishes structures as small as 2 to 3 mm in diameter. Thus, it has became easier to detect the lesion site of pancreatic endocrine tumor by endoscopic ultrasonography. We report the 5 patients who had pancreatic insulinoma which were detected and localized by endoscopic ultrasonography.
